Exploring Multiples and Patterns in Multiplication

This video tutorial covers the concept of multiples, focusing on multiples of 5 and 10. It explains how to identify multiples using factors and provides practical examples, such as counting strings for toy banjos and calculating sticker costs. The tutorial also demonstrates using bar models and tally marks to find products and discusses the commutative property of multiplication, emphasizing that the order of factors does not affect the product. The video concludes with a summary of key points and encourages students to apply these concepts in their schoolwork.

What does the commutative property of multiplication state?

• Multiplication is not related to addition

• You can multiply numbers in any order and get the same product

• The product of two numbers is different if the order is changed

• You can only multiply numbers in one specific order

Which of the following is an example of the commutative property of multiplication?

• 5 / 3 = 1.67 and 3 / 5 = 0.6

• 5 - 3 = 2 and 3 - 5 = -2

• 5 x 3 = 15 and 3 x 5 = 15

• 5 + 3 = 8 and 3 + 5 = 8
